Luke 23:9 Then he questioned with him in many words; but he answered him nothing.
Jesus said nothing to Herod, who wanted a miracle or a trick. Isaiah the prophet prophesied 700 years earlier of this meeting.
Isa 53:6 All we like sheep have gone astray; we have turned every one to his own way; and the LORD hath laid on him the iniquity of us all.
Isa 53:7 He was oppressed, and he was afflicted, yet he opened not his mouth: he is brought as a lamb to the slaughter, and as a sheep before her shearers is dumb, so he openeth not his mouth.
Luke 23:10 And the chief priests and scribes stood and vehemently accused him.
Altogether shouting, loud and angry and in so doing serving satan. Hanging out with others as you are, doesn't make you right. A child of God needs godly friends. Jesus suffered abuse alone for our sins.
Luke 23:11 And Herod with his men of war set him at nought, and mocked him, and arrayed him in a gorgeous robe, and sent him again to Pilate.
John 19:2 And the soldiers platted a crown of thorns, and put it on his head, and they put on him a purple robe,
John 19:3 And said, Hail, King of the Jews! and they smote him with their hands.
John 19:4 Pilate therefore went forth again, and saith unto them, Behold, I bring him forth to you, that ye may know that I find no fault in him.
John 19:5 Then came Jesus forth, wearing the crown of thorns, and the purple robe. And Pilate saith unto them, Behold the man!
Luke 23:12 And the same day Pilate and Herod were made friends together: for before they were at enmity between themselves.
Note this, the two never got along but because they were enemies of God they became friends. I have seen this numerous times in the Internet Christian chats. Those opposing Jesus who have nothing in common, but their opposition, become friends and one in their mockery. The old saying, birds of a feather flock together. The fowls who destroy the word come together, big and little, vulture and crow, with one purpose.
Luke 23:13 And Pilate, when he had called together the chief priests and the rulers and the people,
Luke 23:14 Said unto them, Ye have brought this man unto me, as one that perverteth the people: and, behold, I, having examined him before you, have found no fault in this man touching those things whereof ye accuse him:
Luke 23:15 No, nor yet Herod: for I sent you to him; and, lo, nothing worthy of death is done unto him.
Pilate again attempts to get away from the Jews demand for the life of Jesus. He saw no wrong in him. Nothing worthy of death.
